Abstract

The utility model relates to a medical instrument, in particular to a safe butterfly-shaped venous infusion needle for clinical puncture infusion, which has the advantages that the structure is simple, a discarded hour hand head can be retracted into a needle sleeve, and infection is avoided. The utility model adopts the technical scheme that the safe butterfly-shaped venous infusion needle comprises a needle head with a dish-shaped handle and a safety housing with a hollow structure, and is characterized in that a buckle and a clamping groove which are matched with each other are arranged at the bottom of the inner side of the safety housing and at the tail part of the needle head with the dish-shaped handle respectively, and after an infusion needle is discarded, the needle head is pulled backwards through a butterfly-shaped flank, so that the needle head is retracted into the safety housing and is locked through a buckle structure, and the potential safety hazard caused by nosocomial infection is prevented; and moreover, a clamping device is arranged, so that when the safe butterfly-shaped venous infusion needle is in use, the needle head is not easy to slide in tandem, and the infusion is ensured.

Description

A kind of safe buttferfly-type venoclysis needle

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of venoclysis needle of clinical puncture transfusion usefulness.

Background technology

The buttferfly-type venoclysis needle is a kind of clinical transfusion device of extensive use at present, compares traditional fluid delivery apparatus, and the both wings design of butterfly type handle is more solid and reliable with immobilization with adhesive tape venoclysis needle position the time.

But buttferfly-type venoclysis needle of the prior art also has potential safety hazard, promptly handles when discarding remaining needle, and its syringe needle exposes, and pricks the medical worker easily, thereby causes infection, and its consequence maybe be very serious.

Summary of the invention

The purpose of this utility model is, provides a kind of simple in structure, in syringe needle can be withdrawn needle guard when discarded, avoid pricking the medical worker, stops nosocomial infection, the buttferfly-type venoclysis needle of safety.

For achieving the above object; The technical scheme that this utility model adopts is: a kind of safe buttferfly-type venoclysis needle; It is made up of syringe needle and Secure Shell with dish-shaped handle; Said Secure Shell is a hollow structure, it is characterized in that: the base of said Secure Shell is provided with syringe needle and moves guide groove, and said base is respectively equipped with buckle and the draw-in groove that cooperatively interacts with afterbody with the syringe needle of dish-shaped handle.

Said base open front, its head is provided with annular guard ring, and the middle part is provided with the clamping hurdle.

The afterbody of the syringe needle of the dish-shaped handle of said band is provided with the boss that cooperates with the clamping hurdle of base.

The beneficial effect that this utility model produced is: after venoclysis needle is discarded, syringe needle spurred backward, its syringe needle is contracted to Secure Shell through the buttferfly-type flank, and locked through buckle structure, avoid syringe needle to expose, prevent nosocomial infection.In the piercing process that syringe needle uses, can make it be difficult for moving forward and backward and rotating through clamping fixed needle position, hurdle.

Specific embodiment

This utility model by Secure Shell 1 with form with the syringe needle 2 of dish-shaped handle; Referring to Fig. 1, this Secure Shell 1 comprises two parts of one-body molded loam cake 12 and base 11, and loam cake 12 is shorter than base 11; Base is provided with syringe needle and moves guide groove; Both are provided with the buckle structure that matches, and the back that interlocks forms the hollow structure of base open front, referring to shown in Figure 2.The inboard of the base 11 of Secure Shell 1 is respectively equipped with the buckle 21 and draw-in groove 111 that cooperatively interacts with afterbody with the syringe needle of dish-shaped handle; The head of base 11 is provided with guard circle, after remaining needle is discarded, through the buttferfly-type flank syringe needle is spurred backward; Its syringe needle is contracted to guard circle; And locked through buckle structure, avoid syringe needle to expose, produce potential safety hazard.Be provided with at the middle part of base 11 and clamp hurdle 112, be provided with and clamp the boss 22 that hurdle 112 cooperates with the afterbody of the syringe needle of dish-shaped handle, when user mode, both clamp, and avoid when infusing, and syringe needle moves forward and backward and rotates.

Claims
